AUTOMATIC FIRE-EXTI NGUI SHER- SPECIFICATION forming part of LettersPatent No. 319,774, dated June 9, 1885.

Application filed April 2, 1885. N0 model.)

To all whom it may concern:

Be itknown that I, CHARLES BARNES, a citizen of the United States, and aresident of Dayton, in the county of Campbell and State of Kentucky,have invented certain new and useful Improvements in AutomaticFire-Extinguishers, of which the following is a specification.

My invention is an improved distributer for automaticfire-extinguishers. Its object is a compact reliable device that costsbut little in labor and material to construct, requires no skilled laborto fit to its place, and while being very sensitive to heat is notliable to get out of order. These objects are attained by the meansillustrated in the accompanying drawings, in which Figure 1 is a radialsection of the shell and a longitudinal elevation of the valve andvalverod, the parts being shown detached- Fig. 2 is a similar view ofthe shell cast in one piece, with the valve in place, which isalso shownin elevation here. Fig. 3 is a similar view of the shell shown in Fig.2, with the'valve shown in Fig. 1, and a different means for adjustingand holding the valve to its seat.

Referring first to Fig. 1, the cylindrical shell A, cap a, neck a, andbrackets a are cast in one piece. When the shell is cast, thecylindrical body meets the cap a in a straight line, and the lineconnecting the outer rim of the cap with the cylindrical body is aslightly-obtuse angle, to permit the shell to be drawn easily from themold. After the shell is molded it is centered in the lathe and theupper side dished out, as shown, cutting entirely through thecylindrical shell to form the discharge-port, and thus leaving the cap,neck, and shell connected by the brackets a only. On top of the valve Bis a rubber cup-valve, O, which enters the piece D, by which thedistributer is secured to the end of the dischargepipe. Its upper end,01, is screw-threaded for this purpose, while its lower end, d, isthreaded to screw into the top of the cylinder A. A wrench-seat, (Z isleft between the threaded parts for the purpose of securing thedistributer together and to the end of the dischargepipe. The valve-stemb is transversely perforated at its lower end, as is also the neck a, toreceive a pin of fusible material. The parts are fitted together bypassing the valve-stem through the shell A and into the neck a until thetransverse perforations in the stem and neck register. The fusible pinis then passed through the neck and stem, and the piece D is thenscrewed into the piece 1) until the valve B is brought against its seatin the end of the piece D, when the distributer is ready to be attachedto the discharge-pipe.

In Fig. 2 I have sh own the whole distributer cast in one piece. Thesame cup-valve, G, is used; but instead of the valve Bthe upper end ofthe valve-stem b is provided with a rounded head, which enters the borein the part D. When the water is turned into the pipes, the rubbercupvalve will pack tightly around this and prevent leakage until thepin 1) is fused and the valve thrown out of its orifice. The form shownin Fig. 3 differs in having the cap a centrally perforated,screw-tapped, and a plug, E, provided with valve adjusting and releasingattachments connected to it, fitted to the opening. The attachmentsconsist of the bar F, which is rigidly secured to the plug E, and hasone of its ends, f, turned down and slotted to form one leaf of a hinge.The opposite leaf of the hinge is the upturned end of the hinged leverG. The opposite end, f, of the bar F is turned up and vertically slottedto admit the upturned end 9 of the hinged lever G. This end of the leverG is transversely perforated, the perforation registering withtransverse perforations in the end f of bar F, in the position shown inthe drawings, so that when the fusible pin 1) is passed through theseperforations the parts will be held in the position shown until the pinis fused by heat in case of fire. The plug E and bar F are perforated topass the valve-stem b, which rests upon the end of a screw, H, which istapped through the lever G. By this screw the valve is tightened andheld to its seat on the inner end of the tubular neck of piece D. Itwill be seen that in case of fire the pin b will be fused, the valvereleased, and the flow of water turned into the shell A, forced throughthe slot dividing it and the cup or, deflected upwardly and laterally ina thin sheet or spray, and in this manner discharged upon the fire.

The forms of valve and valve-releasing devices are not broadly claimedherein, as the What I claim as new, and desire to secure by L LettersPatent, is-

1. In an automatic fire-extinguisher, the con1- bination, substantiallyas specified, of the dis- 7 tributershell A, deflecting-cap a, andbrackets a, with a valve extending through the distributer shell and capand held to its seat by fusible material.

2. A distributer for automatic "fire-extinguishers, consisting of theshell A, cap a, neck a, brackets a, cast in one piece with the piece D,for securing the distributer to the discharge-pipe, and a valve passingthrough the distributer'shell and held to its seat by fusible material.

3. The combination of the shell A, cap a,

neck a, and brackets a, cast in one piece with v the piece D, with valve0 and stem b, passing through the shell and neck and secured in itsplace by fusible pin b, substantially as specified.
